    Clickable area and icons on top panel stop working after suspend or lid close

    Ubuntu 22.04.2 LTS fully upgraded.
    The icons and clickable area of the top panel do nothing until the machine is restarted - then after the first "suspend" it all stops working again.
    I don't need or want to restart my machine every time the panel stops working.....
    Any solutions?

    Am I assuming correctly if I guess this CPU is Intel?

    If so then try adding "intel_idle.max_cstate=4" to the "GRUB_CMDLINE_LINUX_DEFAULT=" line in '/etc/default/grub" file. The do
    Code:
    sudo update-grub
